Alstroemeria plant named ‘Staflam’

ABSTRACT

A new and distinct cultivar of Alstroemeria plant named ‘Staflam’, characterized by its erect flowering stems; dark red and yellow-colored flowers with dark purple spots and stripes; and excellent postproduction longevity.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Alstroemeria hybrida cultivar Staflam.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a cut flower Alstroemeria, and hereinafter referred to by the name ‘Staflam’.

The new Alstroemeria is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new cut flower Alstroemeria cultivars with strong plant growth, attractive flower colors and excellent postproduction longevity.

The new Alstroemeria originated from a cross made by the Inventor in April, 1995 in Aalsmeer, The Netherlands, of a proprietary Alstroemeria hybrida selection identified as 90T827-1, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as 86F679-1, not patented, as the male, or pollen, parent. The new Alstroemeria was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross in a controlled environment in Aalsmeer, The Netherlands in June, 1996. The selection of this new Alstroemeria was based on its attractive flower coloration.

Asexual reproduction of the new cultivar by root divisions taken in a controlled environment in Aalsmeer, The Netherlands, since June, 1996, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of the cultivar Staflam have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Staflam’. These characteristics in combination distinguish ‘Staflam’ as a new and distinct cultivar:

1. Erect flowering stems.

2. Dark red and yellow-colored flowers with dark purple-colored spots and stripes.

3. Excellent postproduction longevity.

Plants of the new Alstroemeria are most similar to plants of the parent selections. However, plants of the new Alstroemeria differ from plants of the parents in flower coloration as plants of the female parent have lighter red-colored flowers and plants of the male parent have orange-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the cultivar Stabec, disclosed in U.S. Plant Pat. No. 9,041. In side-by-side comparisons conducted in Rijsenhout, The Netherlands, plants of the new Alstroemeria differed primarily from plants of the cultivar Stabec in flower coloration as plants of the cultivar Stabec had pink and white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria. The photograph comprises a side perspective view of typical flowers of ‘Staflam’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants of the new Alstroemeria grown in Rijsenhout, The Netherlands in a glass-covered greenhouse in ground beds. During the production of the plants, day temperatures ranged from 15 to 25° C. and night temperatures ranged from 10 to 15° C. Plants used for the photograph and description were about 12 months from planting root divisions. The photograph and the description were taken during August and September, 2001.

Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
